T 0 all whom it may concern: Be it known'ithat I, HENRYQHEXRICH, of New York city, in the coinity of New York, and in the State of New York, have invented a certain new and useful Improvement in Finger-Ri11gl\iarking Machines, and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, in wlnch- Figures 1 and 2 are respectively a side and end elevation of a machine embodying my invention; Fig. 3 is a view, principally in section, in the plane of the spindle of the machine; and Fig. 4 is an enlarged sectional view of the ring-holding parts, with the tool in elevation, in a plane transverse to the spindle.'

The object of my invention has been to provide a machine for marking finger-rings which shall be capable of marking such rings after they are turned or rolled, and without injuring the outer surface, or distorting their place by a nut 13.

shape; and to such ends my invention consists in the finger-ring marking machine hereinafter specified.

In carrying my invention into practice, I

rovide a frame 10, having bearings for a 10ll0\\' spindle 11. A gear 12 is keyed on the rear end of said spindle, and is secured in The gear and spindle are adapted to be driven by a pinion 14, on whose sleeve is secured a crank 15, the pinion and sleeve being mounted on a stud 16 that is secured to the frame.

Other forms of driving mechanism for a spindle can, of course, be employed. The gear prevents forward movement of the spindle, and a collar 17 secured upon the spindle close to one of the bearings prevents movement of the spindle in the opposite direction. The shank of the tool 15 is mounted in the forward end of the spindle, and is prevented from rotation relative to the spindle by a set-screw 19. The tool projects beyond the forward end of the spindle, and has formed thereon a die 20, by which the impression is to be made on the inside of the ring. The die is raised above the surface of the shank of the tool, and the shank is of such diameter that the die does not extend around 5 its entire circumference, for a purpose to be later explamed.

In order to support the ring, and to prope-rly present it to the die, the following means are provided: A pair of guides 21 is formed on the frame, and the vertical arm of a bracket 22 is mountcd'on such uides. Means are )rovidcd for raising and lowering the brac 'et on the guides 21, the means which I have chosen as most convenient being a screw 23 that is threaded into the bracket parallel to the guides, and that has its lower end journalcd in a socket in the frame. The screw .is provided with a hand-wheel 24 for turning it. Obvrousl the screw could be screwed into the brac rot and threaded into the frame, and the same results would be produced. The bracket has a horizontal arm 26 in which are formed a pair of guides 27 parallel to the spindle. A slide 28 is mounted in the guides 27,,and is provided with a box 29, whose bottom is formed on the arc of a circle. \Yithin the box aremounted a series of rollers 30. These roller may, if desired, be mounted upon )istons, but I prefer to leave them loose in the box, so that they may roll upon its bottom. A ring-holder 31 rests upon the rollers, the line formed by the upper surfaces of such rollers being the arc of a circle of the same curvature as that formed by the inner )oints of the series of rollers. The ringllOldQl has an inner surface 32 that is concentrio with the outer surface, and that has in it s roove 33 of such cross section as to accurately fit the ring to be marked. The ringholder preferably forms but part of a circle,

but it could be made to form a complete circle. 4 I find it practicable to use but a single ring-holder for a series of rings of differentdiameters, but of the same cross section. In .order to adjust the ring-holding groove directly under the die, I provide a thumb-screw 34, which is threaded'into the slide, and is adapted to extend through the slide and strike against the frame. .A thumbmut 35 serves to lock the thumb-screw 34 in adjusted position.

In the operation of the above illustrated embodiment of my invention, the slide is re tracted until the ring-holding groove is out from beneath the die, and the ring is then placed in said groove. The spindle is turned so that the die is on its upper side, and the slide is moved toward the frame, carrying the ring beneath the die. Because the die does not. extend entirely around the shank of the tool, it is out of the way when it is turned or NEW YORK,

It \vrll be observed that while the series of rollers etl'ectivelv supports the ring-holder against great pressure, it permits the rin'gholder to nrove with such case that there, is 3 no danger of dragging the ring in the ring- It will also be observed' that one ring-holder can be substituted for Q holding groove.

Having thus described my invention, I claim,

1. In a ring-marking nraclrine, the combination of a spindle having a die mounted 1 thereon and extending partonly of a circle, a i ring-holder having a ring-receiving groove, f and a slide carrying said ringdtolder, said i 1 centricwiths t slide being movable parallel to said spindle.

2. In a ring-marking machine, the combination of a spindle havmg adre mounted ion which sard box is mounted, a bracket thereon and extending part only of a circle, a

rotatable ringdrolder having ariug-receivmg f groove. and a slide carrying said ring-holder,

said slide being movable parallel to said spindle- 3. In a ring-marking maclune, the cornbrnatiorr of a spindle having a die mounted tion as the ring, and m ans permitting movement of said ringdrolder concentric with said g j groove. out any vertical movement of the bracket. j

4. In a ring-marking machine, the combination of a spindle having a die thereon, an arc-shaped ring-holder having a ring-holding groove of substantially the same cross section as the ring, and means permitting the movement of said holder concentric with said groove. v

5. In a ring-marking machine, the combination of a spindle having a die thereon, a

ring-holder having a ring-holding groove The slide is then retracted, and the marked and rot-ans for adjusting said holder paralle and transverse tosaid spindle.

6. In a ring-marking machine, the combination of a spindle having a die thereon, a. rotatable ring-holder having a rin holding groove, and means for adjusting sard holder parallel and transverse to said spindle.

7. In a ring-marking machine, the combination of a spindle having a die mounted thereon and extending part only of a circle, a further be noticed that the rings are placed in Q the ring-holder and carried beneath the die i and then removed after being marked, with The ring-holder eil'ectively supports the ring so that the die does not distort the ring either laterallyor longitudinally. j 'hile I have described what I consider to h the best embodiment of my invention, I j lesire it to be understood that the principles i can be embodied in dillerent forms, and I desire not to be limited beyond the requirei S. In a ringanarking machine, the cornbination of a spindle having a die mounted thereon and extending partonly of a circle, a ring-holder having an arc-shaped ring-holding groove and having an outer surface concentric with said groove, :1 box having a curved bottom, a series of rollers mounted in said box and supporting said ring-holder, and a slide on which said box is mounted, said slide being movable parallel to said spindle.

9. In a ring-marking machine, the combi nation of a spindle having a die mounted thereon and extending part only of a circle, a ring-holder having an arc-shaped ringholding groove and having an outer surface corrl groove, a box having a curved bottom, a series of rollers mounted in said box and supporting said ring-holder, a slide movable on. the frame of the machine transi verse to said spindle, and a guide-way on said bracket paraliel to sard spindle, said slide being mounted in said guide-way.

In testimony that I claim the foregoing I have hereunto set my hand.
